Be it known that I, FRANK C. PERKINS, a

v citizen of the United States, residing` at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement lin Bicycle Tool-Bags, which is fully set forth in the following' specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my tool-bag attached to a bicycle and closed. Fig. 2 is a Vertical section of the bag unattached and open. Figs. 3 and 4 are plans of the leather blanks from which the two shells of my toolbag are constructed. o

The object of my invention is to make a bicycle tool-bag which can be attached in the most convenient and least conspicuous part of the bicycle, which is easily opened and closed, and is both simple and economical in manufacture.

It is a further object of my invention to provide a tool-bag wherein the Sections comprising the same have a telescopic connection one with the other, so as to adapt themselves to accommodate more or less tools and of being able to tightly clamp such tools therein by drawing the sections close together, thus preventing rattling of such tools or other articles placed within the bag.

My tool-bag is made in two shells, an inner A and an outer B, each built up from a blank, usually of leather, that for the inner shell being shown in Fig. 3 and that for the outer in Fig. 4. The inner blank consists of a back M, with two end flaps 'm and m', a lateral fiap M', with two end flaps m2 and m3, and a second lateral fiap M2, with end flaps m4 and m5. The blank for the outer shell is similar in form. The part N is pierced with the slits pp' and the end fiaps `na and W; with the slits q and q', respectively- To construct the toolbags from these blanks, the flaps M' and M2 are bent up to right angles with M. m2 and m4 are then bent together at right an gles with M' and M2, respectively,` so thatthe one end flap is partially superimposed upon the other and are retained in this position by a rivet 1-13. The end fiap 'm' is now bent up to approxiflaps m3 and m5 are bent together at right anglesuwith M' and M2, respectvely, so as to be partially superilnposed upon each other and upon M', where they are held by rivets H, I-I', and E2. The fiaps of the blank for the outer shell N', NZ, n', ns, and nfiare similarly bent and riveted together. The end flaps 112 and 714 are then bent together at right angles with N' and N13, after which n is bent up, and the three are held together by one or more rivets 13. The said rivets lS also pass through the end flap n of the inner shell, as shown in Fig. 2. Thus the inner shell is Ahinged to the outer at the point X. .To prevent the shells from opening too far, their upper portions are secured to each other by the strap T, attached to the inner shell by the rivet H and to the outer by the rivet T'. d To retain the shell A within the shell B when the tool-bag is closed,

astrap-and-buckle device R is used, consistin'g of a Strap R' (shown in Fig. 1) and a buckle R2, (shown in Fig. 2,) attached to opposite sides of the outer shell. To facilitate opening the bag, a button S maybe attached to the back of the inner shell.

My tool-bag is designed to lit in that angle of the framework of a bicycle made by the horizontal brace O and the more or less upright brace D. The bag will thus be partially under the seat F and will be almost wholly concealed by the person of the rider. To retain the bag in this position, the two strapand-buckle attachments P and Q may be used, consisting, respectively, of buckles P' and Q' and straps l?2 and Q2, the said straps being` passed, respectively, through the slits p p' and q q' and buckled about the frame elements D and C, as shown in Fig. 1.

In cutting the blank for the outer shell the shape of the flaps N' and N2 will be determined by what is the usual angle between O andD of the frame. The blank for the inner shell will bc so cut that from the piVot-point X the lines X Y and X Z shall beequal to each other and approximately to the line X V.`

It is thus apparent that my tool-bag is economical in construction, dispensing with all sewing, and requiring no skilled and but lit-4 tle manual labor; it `opens readily, assisted mately a right angle with M and the end therein by the action of gravity, and remains IOO open while yet retaining perfectly its contents; it maybe made of any size, and in any given size its capacity maybe decreased or increased by strapping the two shells more or less closely together upon the principle of the traVeling-telescope.

In the construction of tool-bag hcrein shown and described it will be noted that the sections comprising the same are of substantially equal dimensions, each diininishing` in depth toward the bottom', and one telescoped within the other. The object of this constrnction is twofold: First, the shells being practically wedge-shaped, the tools placed in the bag will fall to the bottom and be wedged therein, and, secondly, owing to the telescopic connection of the two shells, they can be tightly drawn together to firrnly hold the tools and prevent all liability of rattling.

That I claim as my invention, and desire to secure by Letters Patent, iso 1. A bicycle tool-bag consisting of two shells of snbstantially equal dimensions, diininishing in depth toward their lower ends, and each having an open inner side, one of said shells being hinged at its lower end to the lower open portion of the adjacent shell, so as to have a telescopic connection therewith, and means for attaching one of said shells to the frame of a bicycle, snbstantially as described.

2. A bicycle toolbag .consisting of two shells of substantially eqnal depth, and each having an open inner side, one of said shells being provided at its lower portion with a fiap made integral with its body, said fiap being secured within the bottom portion of one of said shells and serving as a hinge connection between the two shells, .the parts being so arranged that one telescopes within the other, a Strap secured within the two shells to limit their ontward opening movement, and means for attachin g one of the shells to the frame of a bicycle, snbstantially as described.

3. -A bicycle tool-bag consisting of two shells, each shell constructed from a single blank, comprising a back portion, M; side fiaps, M' and M2; and end fiaps, m, m', m2, m3, m4and m5,' the fiap, m serving as a hinge by which the inner shell is hinged, at its lower end, within the onter shell, and adapted to swing downward and ontward to open said tool-bag.

4:. A bicycle tool-bag consisting of two independent shells of substantially eqnal dimensions and diniinishing in depth toward the bottom and each having an open inner side, one of said shells being provided at its bottom with a fiap made integral with its body, said flap being secured to the bottom portion of the adjacent shell and serving as a hinge connection between .the two shells, the parts being so arranged that one telescopes `within the other and 'the open side of the inovable shell closing toward the rear Wall of the stationary shell, snbstantially as described.

5. A bicycle tool-bag consisting of two counterpart shells of snbstantiall'y eqnal diinensions and diininishing in depth toward the bottom and each having an open inner side, means for attaching one of said shells to the frame of a bicycle, lthe other shell being hinged at its lower end to the lower Vopen portion of the stationary shell so `,as to have a telescoping` connection therewith, the open inner side of the movable shell closing toward the rear wall of the stationary shell, and means for limiting the swinging open of the said movable shell, snbstantially as described.
